Hello everybody,
for
Integrate[ -1 + Cos[\[Theta]]\^2 + Sin[\[Theta]]\^2,
\ {\[Theta], 0, 2 \[Pi]}]
I get the result
ComplexInfinity
though the result is obviously zero. The Calculation is OK if I remove
one of the three terms, such that the result is no longer zero.
Is this a bug?
Thanks
Alexander
